title: [Ultrastructure and cytochemistry of primordial germ cells involved in migration in dichlorvos-treated quail embryos].
abstract: In dichlorvos-treated quail embryos, the ultrastructural cytochemistry of gonads reveals perturbations in the glycoconjugate distribution. The modifications observed concern the surface and matricial glycoconjugates of tissues involved in the primordial germ cells (PGC) migration. In treated embryos, these cytochemical alterations could explain a delayed migration of PGC to germinal anlage and their disturbed settling into gonads.
